Bone (???)

Ok, so we don’t know exactly when and where this went down, but we all know it happened. Two cavemen had a dispute that led to violence…and in this melee, one caveman wrapped his brand new shiny opposable thumbs around a bone, stick or sharp rock and discovered that the damage he could inflict on his fellow man increased exponentially. No longer would combat be restricted to teeth, claws, fists and feet. The age of weapons had begun.
